Title: Train detecting device
Inventor: MARUYAMA KOJI
IPC: B61L1/06
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a train detecting device capable of generating a specified vibration frequency in a rail, and detecting the presence or absence of a train on rails based on the presence or absence of detecting the vibration frequency. SOLUTION: The receiver body 12e constantly judges whether the vibrations detected at two points are the vibration waves of specified frequency generated in a rail 14b by a vibration generator 11a, or not based on vibration data in triaxial directions, inputted respectively from two vibration wave sensors 12a, 12b. Then, when at least either or more of the vibrations detected at the two points is judged to be the vibration waves of specified frequency, it is judged that a train is not operated on the line, and a signal of the presence or absence of the train, the signal level of which is 'Hi', is outputted.  Further, when the vibrations detected at the two points are judged to be not the vibration waves of specific frequency, it is judged that the train is operated on the line, and a signal of the presence or absence of the train, the signal level of which is 'Low', is outputted to a signal or a train safety control system, or a train operation control system, etc., through a repeater 13.

IPC: G02F1/137
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To decrease the influences of reflection by electrodes and to improve the contrast in a cholesteric liquid crystal display device. SOLUTION: In the display device 10, signal electrodes 4a are formed on a substrate 2 and scanning electrodes 5a are formed on a substrate 1, both in the substrate plane direction and facing each other. Then a cholesteric liquid crystal 3 is injected to the space between the substrate 1, 2. When an electric field is not applied between the electrodes 4a, 5a, the cholesteric liquid crystal 3 is in a planar state and the axis 3h of the helix is perpendicular to the substrate plane. An electric filed over the threshold is applied perpendicularly to the axis 3h of the helix by a driving circuit 20 to align the liquid crystal molecules of the cholesteric liquid crystal 3 in the parallel or perpendicular direction to the substrate plane. Thus, the cholesteric liquid crystal 3 is changed into a transparent state.  Since the electrodes 4a, 5a do not cover the pixel plane, a transparent electrode such as an ITO electrode is not required and various kinds of metals can be used.

Title: Winding apparatus
Inventor: DOUSAKA AKIRA
IPC: B65H54/02
Filed: 1983-04-20
Abstract: PURPOSE:To realize high speed automated winding operation by a method wherein a wire is inserted into a hole of a core and a suction pipe by an air flow caused by vacuum suction and a leading end of the wire is positioned while being reformed into straight form and the leading end is guided to the hole of the core. CONSTITUTION:An end of a wire 4 penetrates a hole 2 of a core 1 with an air flow caused by vacuum suction. Because the air flow which flows into the hole 2 from the circumference is formed on one side of the core 1 when the air is sucked, the tip of the wire 4 may be positioned near the hole 2 and the accurate positioning is not necessary. In the following transfer process, a suction pipe 6 holds the wire 4 with a friction given by a pair of holders 30 and, while still holding the wire 4, retreats and then turns around from one side of the core 1 to another in order to transfer the wire 4 to the winding direction of the core 1. As a pair of holders 30 give a certain tension to the wire 4 and wind the wire 4 in the hole 2 of the core 1 while slipping on the wire with friction, the wire 4 is reformed into straight form and wound neatly along the surface even on the crest line of the core 1.

Title: Optical system for magneto-optical disk player
Inventor: MORISHITA ICHIRO
IPC: G11B11/105
Filed: 1990-03-19
Abstract: PURPOSE:To dispense with a 1/2-wave plate and to attain cost reduction and miniaturization by arranging a polarizing beam splitter by inclining by 45 deg. against the tangent line direction of the track of a magneto-optical disk. CONSTITUTION:The polarizing beam splitter 17 is formed in sandwich structure sandwiching polarizing film 17a between glass plates 17b, 17c with same thickness. As a result, it is possible to design an incident angle at 45 deg. same as in the case of using a cubic type polarizing beam splitter though it is a flat plate type polarizing beam splitter. Also, astigmatism can be generated in the convergence beam of light 18 by arranging the flat plate type polarizing beam splitter 17 by inclining by 45 deg. in a convergent beam of light 18 by a convergence lens 6. Therefore, no cylindrical lens is required. Furthermore, since the beam splitter 17 is arranged by inclining by 45 deg. against the tangent line direction of the magneto-optical disk D, it is possible to dispense with the 1/2-wave plate for 45 deg. rotation of a polarizing plane, which attains the cost reduction of an optical system.
